Part Number: DRV8870 Other Parts Discussed in Thread: DRV8231A Tool/software: Hi Team
I have two question about DRV8870.
1. do H bridge need a reverse current protection? or it default need a reverse current so VM need to handle reverse current?
…
Part Number: DRV8870 Tool/software: do you have new PCN for label , left is new coming goods, right is old goods, but label is different. please help check it 。
Part Number: DRV8870 Other Parts Discussed in Thread: DRV8874 , DRV8231A Tool/software: Hi team,
May I get the SOA curve of MOSFET for DRV8874 and DRV8231A?

Hi CA.,
This does seem strange. The device should not be drawing that much current without a load attached. Would like to look more into the schematic just to verify connections. Do you see any noticeable solder blobs or pin shorts near any of the pins…
Part Number: DRV8870 I am working on a project where I plan to use the DRV8870 motor driver to control multiple motors (14 DC brushed motors) in a single direction. I intend to connect the DRV8870's OUT1 to the input pins of 14 motors, using a shared…
Part Number: DRV8870 Hi team,
How to understand OC deglitch time 1.5us in datasheet? It means when current is over 3.7A, but device will not trigger OCP immediately, and FET can stand >3.7A current for ~1.5us with FET never being broken down?
Best…
Part Number: DRV8870 Hi team,
When I use DRV8870 in coast mode(fast decay freewheel), there is peak current>6A, even 8A, duration time is < 2uS as below, but not trigger OCP. so I want to what is the current limit of the body diode in this mode? …
Part Number: DRV8870 Hello,
My customer encountered an issue where the DRV8870 was damaged while testing its operation.
* Symptom
1. Back electromotive force is generated while changing direction without brakes.
2. As the PWM increases, the value of…
Part Number: DRV8870 Hi Team,
When the motor is working and INT is low, why does OUT have a narrow output? The customer's understanding is that there should be no output.

Part Number: DRV8870 Hello,
My customer is testing the DRV8870 operation on their custom board.
They designed as below.
- Sense Resistor = 0.1R, Vref = 3.3V, Current limit setting = 3.3A
It is confirmed that the 3.3A limit is applied to the motor outputs…
